I guess that we have signed Leman to our practice squad because this is now the second site that has posted it. I think in the up coming weeks, we will release one of the LB's to add depth to another position

The odd thing is that the Eagles have him listed as on their practice squad.:

I was hoping we would find a way to keep this guy on the active roster. He had more intensity then i have seen from our D in a long time.

I believe he is on the Eagles practice squad and not ours.  In order for us to have put him on our practice squad we would have had to have signed him to the practice squad first.  To claim him off of the eagles squad we would have to put him on our 53 team roster.  I believe the Eagles are picking him for info for the first game.
